GRAIN-BINDER.

SPECIFICATION forming part of Letters Patent No. 269,004, dated December 12, 1882,

Application filed April 15, 1882. (Model.)

To all whom it may concern:

Be it known that 1, JOHN E. BUXTON, a

' citizen of the United States, residing at Owatonna, in the county of Steele and State ofMinnesota, have invented certain new and useful the machine being considered for the present purposes the front. Fig. 2 is a perspective view from the right-hand side of the machine, the delivery end of themachlne being considered for present purposes the front. Fig. 3 is a bottom plan of the machine. Figs. 4 and 5 are views of the knotter; Fig. 6, a detail in perspective to show the knotter and the twineguide, the discharge-arm, and the retainingarm.

This invention belongs to that class of devices known as grain-binders, and the novelties and particular points of invention and improvements will be now more fully set out and explained.

The device being in many particulars like that shown in my Patent No. 248,401, will in those particulars be now only described so far as is necessary to set out fully and clearly the construction and operation of the features or parts which are new and on which secure a patent.

In the accompanyingdrawings, A is any suitable frame to hold this machine, and B the I wish to "floor of the binder. The main shaft by which motion is imparted to the partsof the machine which form the gavel and do the binding is shown at G; and D is the shaft on which are eccentrically fixed the disks e, carrying with a reciprocating motion the packer-arms F.

The two shafts O and D are connected by a sprocket-chain, g, or in any other suitable way, and are driven by anyconvenient power. The disks 0 are so mounted on shaftD as to insure an alternately reciprocating movement to packer-arms F, the outer or upper ends ofeach of which embrace by a loop, f, said disks. An increased steadin'ss is given to these movements ofsaid arms and packers by having their outer ends, f, placed in hearings in bar a, which is suitably connected with the main frame A. The forward ends of said packer-arms have a suitably-curved outline to be readily adapted to engage upon or behind the incoming grain-stalks, and by the reciprocating motion aforesaid push them forward and against the gavelforming arm H near the front edge of the machine. The packer-arms F move in guides 70, and thus precision of action is secured. The arm H is curved, and while the gavel is being formed projects up through the slot a in the floor of the binder. The arm 11 is secured upon one end of the shaft I. This shaft is suitably mounted in bearingsunder the floor of the binder, and at its opposite end is connected by arm -i and a suitble link, '5, and arm 11" with the cam-wheel L on the right-hand side of the machine. When the binding of the gavel is finished the cam Z on the face of wheel L has come in contact with the pin 1" of arm 1', and thus the shaft I is rocked, and the arms X attached to it coming up through the binderfloor eject the gavel from the machine. Simultaneously with this the binder-arm is retracted. In the further rotation of cam-wheel L the cam 1 passes the pin 77', and the latter comes inside the cam Z. This cam, by reason of its peculiar shape, operates (just before wheel L has ceased to revolve) to give motion to the arm '5 and cause the shaft I to be rocked, and thus retract the arms X and alsobring up arm H. The pin 2", when wheel L again starts to rotate, is carried along inside that part of said cam I which is concentric with the wheel, and the arm i is at rest and arm H held steady while the gavel is being made and tied. k

The needle or cord arm M is attached to the shaft Q, which is actuated by means of the link g on the left-hand side of the machine connecting with the arm 0 on the end of shaft 0. The lower end of this link (1 is slotted and works on a pin in the arm g at end of shaft Q, and produces the necessary intermittent motion of the needle or cord arm.

()n a spring, q, is a stud, 9 which, when the binder-arm is elevated, is pressed into a slot or indentation in arm q, and thus locks the binder-arm shaft while the binder-arm is around the. gave], and the spur g on link q in thedownward movement of the link acts on the spring q. to release this stud from said position at the desired moment.

The knotter R, having jaws r for the cord, is properly mounted in the machine by means of the socket 1 and strap 2, in which its shank is placed vertically to receive actuating motion from the gear-teeth on wheels 0 fixed on shaft 0 and which gears withthe pinion r of said knotter.

It willbe seen in Fig. 4 that the knotter is composed of three jaws-one upper and two lower-and between the two lower jaws is pivoted the tongue 4", which is held closed by spring r to retain t e cord; or the knotter may have only two jaws, the lower one slotted for the reception of the tongue W. The upwardly-extended part r of this tongue will in the revolution of the knotter come at the proper time against a suitable cam, w which lowers the tongue to allow the ends of the cord (held by the grasper N) to come between it and the upper jaw, the tongue being immediately closed against the upperjaw by spring r and the cord ends are thus held till theloop is pulled off and the knot formed.

Tue cord-guide P consists of a pair of open 0 jaws or fingers a, fixed on the end ofthe vertical shank 9, so as to come near the knotter. This shank has a square side, 19 against which the arm 0 on shaft 0 strikes as the cord-arm comes up over the gavel. As the cord-arm M approaches in its forward movement, the guide is turned about one-quarter round by means of that part of arm 0 which is at right angles to the shaft G. This engages on the side 12 and brings the guide under the knotter, the curved part of the arm 0 bearing against one of the square sides 19 holding it in that position during the completion of the knotting operation immediately after the curved part of (J has passed from contact with square 19 until the bent arm O fixedon the shaft O,oomes against the spur p on the shaft of the guide and turns the guide-jaws outward. At the same time the spur c on' the inside of the arm 0 engages the pinion of the knotter, turning it about one-quarter round in the same direction. Thus the cord is allowed to fall off the knotter and out of. the jaws of the guide. The guide is now returned to its original-position by means of the arm 0 on shaft 0, which engages on the spur p on the guide-shaft, and the guide is again ready for the cord of the new gavel. Theforked end of the guide-arm a; be tween the grasper and the knotter serves to guide the cord into the jaws of the knotter. When the cord-arm M has come up and over the gavel and placed the cord in the slot win the grasper N said grasper is retracted by the reciprocating movement derived through its connectinglever-arm Z, actuated by apin inits opposite end playing in the cam-path of wheel Z, which wheel is fixed on the shaft 0. This movement of the grasper serves to hold the through a slot 0, in which the grasper has reciprocating movement. While the end of the cord is thus held in slot at of the grasper, the cord-arm M is carried back to await theformation of another gavel. At its return the cord falls into the jaws p of the cord-guide P, which jaws are now turned so as to point on either side of the returning arm M, and thus the cord is held in safe position while the grain-stalks are being packed against the arm H. When the cord has been placed in the holding slot at in the grasper N, the grasper is retracted by the lever-arm Z. actuated by a pin in its opposite end playing in the cam-path of wheel Z on shaft (3.. This movement of the grasper serves to hold the end of the cord against the face of arm 0 through a slot, 0, in which the grasper plays, as aforesaid. The cord is cut by the spring-knife n on the side of the grasper opposite the holding part a, the cutting being done between the knife and part 0.

The shaft D, which gives motion to the packer-arms, is mounted-in movable bearings d, and has a spring, a, against one sideof each of said bearin gs. The stop a will prevent too far rear motion of said bearings. These springs will not only act on said bearing to keep the shaftD well toward the knotter, but, by reason of the arm V being pivoted to the right-hand bearing d below its pivot 61*, will operate to retract said arm at the proper moment. After the tied gavel has been thrown 0d the binderfloor by the arms X, which are attached to and actuated by the shaft I, and at the proper moment, as the arm H retires, come up through slots in the binder-floor for this purpose, these arms retire and arm H is again brought above the floor, and the new gavel formedagainst it by the operation of the packer-arms. During this operation of forming the gavel the latchhead Q), on the end of the arm V, engaging on the spur w of the clutch, disengages the clutch from the notches on the spoeket-wheel '2 ,which is loosely mounted on shaft 0, and this stops the motion of the cord-operating mechanism. When the packer-fingers press hard enough against the gavel, the shaft D, is forced back,

the arm is pivoted, to swing, and this throws the latch-head o of said arm from between the sprocket-wheel y and the projection to on the clutch W, whereupon said clutch, forced by the spring 10 engages withthe sprocket-wheel y, over which the torward part of the endless chain g passes, its rear part passing over the sprocket-wheel y" on the shaft D, and thus the cord-carryin g mechanism is started into operation. To produce this alternate stopping and starting motion it will be seen that it is necessary to have the'sprocket-wheel loose on the shaft, and the clutch W mounted thereon so that it cannot rotate without rotating the shaft, but yet have a sliding movement longitudinally thereon. Hence the shank of the clutch is slotted, as at to, through which a pin on the shaft 0 projects. When the clutch. en gages, as above,

which movement causes the bearings 61, to which end of the cord against the face of the arm 0,

with the notches on the sprocket-wheel y it will cause the cam-wheel L on the end of said shaft to turn and operate the arms H and X, as above set forth.

The supplemental sprocket-wheel y, which comes under the chain 9 midway between the shafts U and D, works on an arm mountedin bearings 3 which arm is actuated by a spring,

1 for the purpose of keeping the same tension on the chain when the shaft D is moved back by the pressure of the packer-fingers'on the gavel.

Having now described my invention, What I consider new, and desire to secure by Letters Patent, is-- f 1. In a grain-binder and in combination with the actuing-shaft D, on which are mounted the eccentrics e, the packer-arms F, each having loopfand guide eudsf, and operating substan' 4.
